Suno Served with Another Proposed Class Action Over Reported Data Leak

Suno is the subject of another proposed class action lawsuit over the November 2025 data breach that reportedly exposed the personal information of 55.3 million users.

The plaintiff:

• South Dakota’s Michael Beckham filed the suit on September 3 in the US District Court for the District of Massachusetts, where Suno is headquartered.

• He claims to have “experienced an increase in unsolicited spam telephone calls and phishing attempts” since the breach, and “spent approximately ten hours investigating the incident, attempting to protect his other online accounts, reviewing and strengthening account security, monitoring for misuse, and consulting counsel regarding protective measures and his legal rights.”

Context:

• While the data breach occurred in November 2025, it only became public in July 2026 when breach-notification service Have I Been Pwned added the dataset to its database.

• Suno has already been hit with two class actions around the data breach, which were recently consolidated into a single case.

• Beckham’s complaint says his action is related to that consolidated case.

Damages:

• As per Music Business Worldwide, Beckham is seeking damages; complete individualized notice of the information affected; identity-theft, phishing, and account-protection services for “not less than five years”; and prospective security, retention, and deletion measures.

• The filing proposes a nationwide class covering all those in the US whose personal information was included in the dataset obtained from Suno, plus a South Dakota subclass.
